Rucking training plan, with the strength work that holds it up
A ruck is a walk your spine has to hold up. Distance and weight both progress, but never in the same week — and the strength work is not optional extra credit, it is the thing that keeps the pack off your lower back.

The short answer
A rucking plan in phase.fitness is two to three loaded walks a week plus two strength sessions. The endurance side follows the trail and hiking document: most of the volume easy and conversational, one longer ruck that builds time on feet, and one shorter session with hills or a heavier pack. Load and distance move in alternate weeks, never together, because the eccentric cost of a loaded descent is what actually breaks people. The strength side is hinges, split squats, carries and direct trunk work, which is where pack tolerance is built. Rucks are planned as hikes or walks, so they reach a Garmin watch by name.
One variable a week
Rucking has two dials — how far and how heavy — and turning both at once is the classic way to end a block early. The trail and hiking document treats load carriage as an eccentric problem first: the descent under weight is what accumulates damage, and it accumulates faster than the aerobic system adapts.
So phase.fitness moves distance in one week and load in the next, holding the other still. Roughly 10 per cent on the long ruck's time, or two to four kilos in the pack, and never both. A deload week takes the weight out entirely and keeps the walking.
The strength work is the plan, not the garnish
What fails under a pack is rarely the legs. It is the upper back that rounds, the trunk that stops bracing, and the hips that stop extending at the end of hour two. phase.fitness programs hinges, split squats, loaded carries and direct trunk work twice a week for exactly that, from the same strength document it uses for any other block.
Carries get their own line in the plan because they are the closest thing in a gym to the actual event: a load held against a spine that has to stay stacked while you walk.
Should you add weight or distance first when rucking?
One at a time, in alternate weeks. phase.fitness moves load and distance separately and never together, because both at once is how a rucking plan turns into an injury — and it keeps most of the volume easy and conversational, with one longer ruck building the time on feet.
Why do loaded descents hurt more than climbs?
Because the eccentric work of lowering a loaded body is what actually breaks people, and it is the reason phase.fitness writes the hill sessions the way it does: shorter, at the same pack weight, with the descents walked under control rather than run.
What phase.fitness builds
A program is a sequence of phases, each with a job. These are the phases phase.fitness writes for this case, with the bands the generator has to respect — transcribed from the document it reads, not invented for this page.

Event pace
3–4
| Phase | Weeks | Job | Band |
|---|---|---|---|
| Time on feet | 4 | Aerobic base and pack tolerance at a light load | Long ruck 60→90 min at 10–12 kg; strength 3 × 8–10 at RPE 7 |
| Add the load | 4 | Weight climbs, distance holds | Pack to 16–20 kg on the long ruck; strength 4 × 5–8 at RPE 8; carries every session |
| Event pace | 3–4 | Target load at target speed, then back off | Two rucks at event weight, one with hills; deload week with the pack empty |
A sample week
One week from the first phase, as it would sit on the calendar. Your own week follows the days you say you have — 4–5 here — and the equipment you list.
- SStrength
- CCardio
- Rest
| Day | Modality | Session |
|---|---|---|
| Mon | S | Trap-bar deadlift 4 × 6, split squat 3 × 8/leg, farmer carry 4 × 60 m, side plank |
| Tue | C | Ruck 45 min at 12 kg, flat, conversational pace |
| Wed | Rest | — |
| Thu | S | Back squat 4 × 6, single-leg RDL 3 × 8/leg, row 4 × 10, suitcase carry 4 × 40 m |
| Fri | C | Ruck 35 min with hills at 12 kg, walking the descents under control |
| Sat | C | Long ruck 90 min at 16 kg, easy throughout |
| Sun | Rest | — |
S = strength · C = cardio · K = calisthenics. The order is the point: hard days are kept apart and the long session gets the clean slot.
How it adapts when a phase ends
phase.fitness reads the rucks back from Garmin or Intervals.icu — duration, distance, elevation and heart rate — and the strength sessions from Hevy or Liftosaur. Garmin activities are read only if you allow it. If heart rate drifted upward late in the long ruck at a pace that used to be steady, the next phase holds the load and extends the time instead of adding kilos. If the descents are where the pace falls apart, it adds eccentric leg work rather than more rucking.
Where the sessions go
phase.fitness plans; you train in the app or on the watch you already use, and the completed session comes back. For this program:
What phase.fitness does not do here
phase.fitness plans rucks as hikes or walks, which is how a watch records them. It does not model pack weight as a physiological load, so the training effect your watch reports will read lower than the session actually felt.

Frequently asked questions
How much weight should a rucking plan start with?
Ten to twelve kilos for most people, and phase.fitness holds it there for a full phase while the time on feet grows. Weight and distance never rise in the same week in the plan, because the loaded descent is what accumulates damage fastest.
Do I need strength sessions to ruck?
To ruck well, yes. phase.fitness programs two strength sessions a week around hinges, split squats and loaded carries, because what usually fails under a pack is the upper back and the trunk rather than the legs.
Do rucks go to my watch?
Yes. phase.fitness plans them as hikes or walks, which Garmin receives by name, and the completed activity comes back from Garmin. The pack weight is not something a watch records, so it lives in the plan rather than in the file.
The only app that plans strength, cardio and calisthenics together
The bodyweight day here is trunk and upper back: hollow holds, hangs and ring rows train the positions the pack attacks, at loads you can control precisely.
Right now, phase.fitness is the only training app that writes strength, cardio and calisthenics into one periodized program — same calendar, same phases, same recovery budget.
You choose the mix. A calisthenics-only plan, a cardio-only block, strength plus cardio, or all three: the phases, the end-of-phase analysis and the sync work the same way with one modality or three.
Why calisthenics is in the plan
Bodyweight skill work is strength training in a different shape. Straight-arm work, levers and handstands build scapular control, tendon capacity and relative strength that barbell and machine work leave untouched, and they transfer because they are closed-chain, whole-body patterns. Treated as a modality rather than a warm-up, they get sets, holds and progressions like a squat does.
No exercise catalogue on the market contains a tuck front lever, so those sessions run in the phase.fitness built-in player; strength goes to Hevy, Liftosaur or a Garmin watch, cardio to Garmin and Intervals.icu. How the skill work is programmed.
